Cisco 1700 Router

I believe you have not forgotten to set default gateway (your Cisco addresses) on the both ends.

what happened when you issued tracert command?

Several things come to mind and the first answer did not address these.

Your 192.168.0.0/24 subnet is a private subnet. The 100.100.100.0/16 is a public subnet. In order to ping from pub/priv or priv/pub across a router you must be doing NAT.

Your router can see both subnets, which is why you can ping from a console or telnet session to the router. But it cannot forward packets if it is not NATing.

Start with this Cisco article. It will help you understand why things are not working and basic configurations.
